Patented Dec. 25, 1951 FILM REEIQ BAND William E. Murray, Regina,Saskatchewan, Canada, assignor to Saskatchewan, Canada General FilmsLimited, Regina, Canada, a corporation of Application April 24, 1950,Serial No. 157,657 In Canada December 12, 1949 4 Claims. 1

This invention relates to film reel bands such as are employed toprevent a film from unravelling from its reel.

Heretofore it has been the usual custom to hold film on its reel bymeans of a band having a string which is tied or looped about the bandto hold it in place. Not only is the string awkward to apply but it hasa tendency to become untied or to slip over the side of the film anddrop between the film and the inner face of the reel, thus permittingthe band to become loose. In such cases, the film may fall off the reelin shipping and become damaged.

Various attempts have been made to provide more efficient bands.However, such bands are usually subject to one or more disadvantages,such as costliness of production, insufficient security in use, andpossibility of injury to the film.

An object of the present invention is to provide a film reel band whichis inexpensive to produce, which may be readily and quickly applied,which is effective in properly maintaining the film on the reel undersubstantially all conditions of use, and which is non-injurious to thefilm.

The invention will be described with reference to the accompanyingdrawing, in which,

Figure 1 is a side elevation of a portion of a film reel, showing theband of the present invention in place thereon, and

Figure 2 is a plan view of the band.

In the drawing, I illustrates one of the side plates of a film reel ofusual structure and 2 a roll of film thereon. The retaining band 3comprises a strip 3 of heavy paper or like material such as is usuallyemployed in the construction of such bands. An eyelet 4 of metal or thelike is provided closely adjacent one end of the strip. A short portionof the strip is doubled back on itself, as indicated at 5, and theeyelet extends through such double ply portion of the strip, whichconstitutes a reinforced area surrounding the eyelet.

The band 3 is provided with a resilient section comprising a rubberstrip 6 having one end anchored in the eyelet 4. The strip 6 may be anordinary endless rubber band of commercial type. A band similar to acommercial No. 33 band is satisfactory for the purpose, such band beingin unextended condition approximately three and one-half inches inlength and one-eighth inch in width. The rubber band 6 may beconveniently anchored in the eyelet simply by looping it therethrough asshown.

Anchored to the other or free end of theresllient section 6 is a tab 1.Such tab may be 2 formed integral with the band 6 or it may comprise arubber strip which is looped through the end of the loop in rubber band6, and then doubled upon itself with its abutting surfaces adhesivelysecured together.

Mounted in strip 3' intermediate the ends thereof is a hook 8, the shankof which extends through the strip 3 and is clinched on the under sidethereof. Preferably, the mounting of the hook is reinforced by providinga double layer portion of strip 3' in the area of the hook. This iseffected by applying a small piece 9 of heavy paper or the like to theunder side of strip 3, the shank of the hook also extending through suchpiece 9. l

The portion ill of the band 3 between the hook 8 and eyelet 4 has alength somewhat less than the general range of circumferences of thefilm rolls to which the band is to be applied. The remaining portion IIof the band 3 between the hook 8 and the other or free end of the bandhas a length preferably at least as great as the major section of theportion 10.

In use, the band is applied as indicated in the drawing, the tab 1 beingreadily engaged with the hook 8 to hold the band in place. The freelyextending end of the tab is conveniently grasped by the operator toapply or release the tab with respect to the hook. Since the portion H)of the band is always less than the circumference of the film roll, theresilient section 6 is always under tension on application to the rolland. thus a retaining pressure is maintained on the roll to hold itrigidly in place. The resilient section 6 also accommodates the band tovarying sizes of rolls. The portion ll of the band always underlies, inuse, the resilient section 6 and underlaps to a considerable extent theeyelet end of the band, thus affording adequate protection to the film.The end of the shank of hook 8 is embedded in member 9 and thus thereare no projections on'the underside of the band to cause injury to thefilm.

What is claimed is:

1. A film reel band comprising a major inextensible section and a minorelastic section secured to one end of the inextensible section, a tabsecured to the free end of the elastic section, and a hook engageable bysaid tab and mounted in the inextensible section intermediate the endsthereof, the portion of said inextensible section extending from saidhook to the other end thereof having a length greater than the normallength of said elastic section thereby to underlie the entire elasticsection when the band is mounted on a reel.

2. A film reel band comprising a non-elastic strip, an eyelet extendingthrough an end portion of said strip, a rubber band having one endanchored in said eyelet, a tab secured to the other end of the rubberband, and a hook engageable by wherein said rubber band is of theendless type and is looped through said eyelet for anchoring thereto,and wherein said tab comprises a strip of rubber looped through the freeend of said rubber band and doubled upon itself, the abutting faces ofsaid rubber strip being adhesively secured together.
